I've been very happy with mine! After I build up the motor I'm going to push it up to 30 psi

I look forward to the numbers, I hit 469@22.5. Maybe after winter ill get it tuned again at some higher boost and put the built motor threw its paces and see what happens.

If you run ur car on that same dyno and same elevation I bet you put down over 600hp!

That would be intense. I love the power now so another 100whp would be crazy.

You wouldn't gain any HP, every dyno reads differant and that one must read high. I put down 380 mustang dyno with the same setup and elevation with 27 psi on vp109. 140 HP difference is a lot?!?!?

Every car is different this is true. But when it was being tuned I didn't want to push it. And the tune was just getting going. Granted you could be right I won't make much more power... But on the other hand there is more left in the turbo and motor

It reads about right. I've had my car on 2 different dyno jet's and they read about the same.

It sure does! And the 2800lb chassis helps too

robotskillhumans · 11-14-2012, 08:39 PM

I must be doing something wrong. I have a Dom 4 with a built shortblock at 21 psi with all the supporting mods and I'm only making 360 whp. Anyone have any recommendations?

That's on pump gas and meth. I haven't gotten it tuned on race gas yet.

I was at that power level on pump 18@ psi. The turbo really comes alive with higher boost and race fuel helps. My final pump map at 21 psi was 400whp. Built block. Some cars react different to the fuel and so on. I bet the tuner wanted a safe tune for you. But I'm only assuming that.

robotskillhumans · 11-14-2012, 11:16 PM

Well yes they definitely went with a tune on the safe side. I can tell that my tune is on the rich side. All I wanted was 400whp on pump.

On pump I was around 350whp on the DOM3 you should be close on the 4.

I wasn't happy with the low numbers on such a big turbo, that's why I chose to switch to E85

scoobiesnacks22 · 11-17-2012, 11:05 AM

Yea I put down 340 on pump on a mustang, but I only put down another 40-50 on higher boost not another 150!!

A lot of my additional power comes from both AVCS tuning and the additional timing you can run with E85. During tuning I saw numbers come up as much as 30hp from small timing adjustments alone.

What size injectors did you use? I was told that I would need 2000cc injectors to run e85

I'm on 1400cc injectors. But I also have -8 feed lines and a fuelab 600lph pump. The back half really helped keep my IDC's low

What Turbo and power level are you going for?

Blacksheep6 · 11-17-2012, 03:46 PM

You can if you don't plan on running any more then low 20's psi boost range. I ran out of fuel (e85) on a dom 3xtr with a hardwire aero 340 fuel pump at 65 pds base fuel pressure and 23.5 psi boost.

zakeswrx · 12-04-2012, 02:41 AM

I don't think I've read any charts where someone had heads and cams done running the Dom 3.0xtr I'm thinking that will make a pretty decent increase in power
